Compatibility Enhancements

This version additionally passed the test cases in test_fixed_v1.2.2.bash. Moreover, this version passed all of the cases in ifs-posix.tests, which is a test script in Bash official repo. It's amazing.

v1.2.0

Enhanced Compatibility around Variables and Parameters

We have fixed subtle different behaviors between Bash and Sush mainly based on the run-array script in https://github.com/ryuichiueda/bash_for_sush_test/tree/master/tests . We can see the added test cases for this version from v1.1.8 in https://github.com/shellgei/rusty_bash_test/blob/v1.2.0/test_fixed.bash .

  • supported declare -f
  • fixed the difference between Bash and Sush on the handlings of arrays and associative arrays
    • I can't explain these very subtle fixes. Please see the cases in the URL indicated above.
  • fixed out put of declare -p

v1.1.5

Compatibility improvement

We add some features to this shell and fix some incompatible behaviors based on the test in official Bash repo. See additional test cases between v1.1.4 and v1.1.5 in our test.

  • Fixed the behavior of our shell when it is feeded a shell script containing lines that should be read by a command in the shell script.
### example ###
🍣 echo 'cat
> This line is read by the above cat' | sush
This line is read by the above cat
  • Invalidate ANSI-C quoting in here documents
  • Implemented substitutions for every element in an array
### example ###
🍣 set abc abc; echo ${*/a/A}
Abc Abc
  • Enabled to parse $"..." (roughly)
  • Enabled to use declare -r for an element of an array

v1.1.3

Fixed terrible bugs

I'm extremely sorry. That's terrible.

solved calculation problem

The implementation of arithmetic expressions in v1.1.2 has passed all of the tests in Bash repo. However, it mistook the following simple calculation. That is because the calculation was evaluated from the right side, ... and because our repo and Bash repo missed such an easy test case.

### It's wrong. (terrible) ###
🍣 echo $(( 1 - 2 + 3 ))
0

We now fixed and the shell keeps a correct tally.

### calculated from the left side ###
🍣 echo $((1 - 2 + 3))
2
### It must be evaluated from the right side in this case. ###
🍣 a=3 b=3 c=3
🍣 echo $(( a += b += c ))
9
🍣 echo $a $b $c
9 6 3

solved an input mixing problem on source command

It's also terrible. The following is the behavior of v1.1.2.

### test.bash ###
echo OK | ( while read line ; do echo $line ; done )
ああああああ！
🍣 source test.bash 2> /dev/null
ああああああ！      # <- the read command reads the next line of test.bash
OK

It's fixed at v1.1.3.

source test.bash 2> /dev/null
OK

Compatibility Improvements around arithmetic expression, and others

Based on the test in Bash repository, outputs are matched to those of Bash.

Examples

🍣 n=0 a="(a[n]=++n)<7&&a[0]"; ((a[0])); echo "${a[@]}"
(a[n]=++n)<7&&a[0] 1 2 3 4 5 6 7
🍣 unset a
🍣 a=1 ; a[1]=2 ; echo ${a[@]}
1 2
🍣 PARAM=abcdefg; echo ${PARAM:1 ? 4 : 2}

🍣 unset a
🍣 A="a[0]" ;echo $(( ++$A))

🍣 a=1 ; echo $((4+ + +a))
5
🍣 a=1 ; echo $((4+ ++a))
6
🍣 a=1 ; echo $((4+++a))
